Until HCFC-225eb becomes available in commercial quantities, HCFC-225eb may be prepared by a standard and well-known organic synthesis technique. For example, 1,1-dichloro-1,2,3,3,3-pentafluoropropane may be prepared by reacting trifluoroethylene with dichlorodifluoromethane to produce 1,3-dichloro-1,1,2,3,3-pentafluoropropane and 1,1-dichloro-1,2,3,3,3-pentafluoropropane. The 1,1-dichloro-1,2,3,3,3-pentafluoropropane is separated from its isomer using fractional distillation and/or preparative gas chromatography. Alternatively, 225eb may be prepared by a synthesis disclosed by O. Paleta et al., Bull. Soc. Chim. Fr., (6) 920-4 (1986). The 1,1-dichloro-1,2,3,3,3-pentafluoropropane can be separated from its two isomers using fractional distillation and/or preparative gas chromatography.
